- Title
Redundancy in Cortical Surface Vessels Supports Persistent Blood Flow.
- Authors
Gross, Liza
- Abstract
A study published in PLoS Biology explores the resilience and dynamics of blood flow in the brain. Researchers used microscopy and laser-induced clotting techniques to measure blood flow in the surface vasculature of rat parietal cortex. They found that the arteriole network quickly reestablishes blood flow following a targeted occlusion to a surface vessel. The study suggests that the redundant connections between branches of the middle cerebral artery on the cortical surface ensure persistent blood flow and protect against localized occlusions. These findings could have implications for understanding stroke vulnerability in different regions of the brain.
